I am brand new to black powder and have been getting all my accessories. I read a really good review about the Taylor's Italian made inline capper. This thing looks machined and not made from sheet metal! It's heavy duty! But, I can't figure out how to load the darn thing. The "lanyard" loop on the end is not big enough to hold back that "thumb knob" against the spring for loading like others I've seen on Youtube. And that "thumb knob" seems like a really sloppy fit inside the track. Can I get any tips on how to load this thing? Thanks!
